DRINKING WATER CASE STUDIES AND WHITE PAPERS

• ORP And pH — What You Don't Know Can Hurt You

  When I look back at 2016 one of the most significant trends I observed was the growing acceptance of ORP measurements, especially for monitoring disinfection. With one caveat, the ORP value measured in a solution provides an unambiguous measure of the disinfection efficacy.

• What The Industry Is Saying About The EPA Contaminant Candidate List 5

  It is assumed that most individuals involved in the advocacy, treatment, and regulation of drinking water in the U.S. have similar opinions on the importance of delivering clean, safe drinking water. But determining how regulatory steps regarding daily practices at water treatment plants (WTPs) should evolve tends to reveal some differences in opinion. Here are some recent industry reactions to the proposed Drinking Water Contaminant Candidate List 5 (CCL 5).

• Managing Water Loss In Four Easy Steps

  A practical approach to detecting leaks and reducing non-revenue water.

  Water utilities are charged with an incredibly important task – providing safe and affordable water to communities in the face of aging infrastructure, funding gaps, and changing regulatory requirements. Specifically, when considering water loss control, leakage, and operational inefficiencies, costs may appear to be unaffordable.

• Encore® 700 Chemical Metering Pumps Provide Precise Coagulant Metering

  Water utility operators are increasingly challenged by scrutiny and regulation on disinfection by-product (DBP) levels while trying to manage ever increasing coagulant costs in a tight budget environment.

• The Pandemic Shines A Spotlight On The Need For Better Water Quality Management In Office And Commercial Buildings

  Explore the parallels between water systems in buildings and water utilities, and the need for property owners to adopt water quality management practices, such as time-based flushing, to maintain safe water conditions for occupants.

• Turbiwell Comparision Report Before And After Upgrade

  Russellville water treatment plant is a surface water plant using traditional clarification, filtration, and treatment. The plant historically has used traditional contact turbidimeters that employ tungsten lamps that required quarterly maintenance, but replaced their turbidimeters with Swan Turbiwell turbidimeters in 2012. Read the full report for a comparison of the performance of the Swan Turbiwell to the previously installed turbidimeters.

• Two Decades Later, American Ductile Iron Pipeline Keeps Water And Hope Flowing In Potosí

  Nestled at the foot of the Cerro de Potosí – or Cerro Rico (“rich mountain”) – is Potosí, Bolivia. This capital city of the Tomás Frías Province was established almost 500 years ago and is most known for its abundance of silver, which has fueled the area’s economy for centuries. Another unique aspect of Potosí is its location. It is one of the highest cities in the world, with an elevation of more than 4,000 meters [13,000 feet].

• Los Angeles Department Of Water And Power Uses GIS To Improve Water Incident Management

  While utilities use sophisticated systems to supply clean water as well as collect and treat wastewater, the effort to manage incidents and outages leaves room for improvement. Water utilities often rely on manual processes to handle customer reports of leaks, loss-of-service or quality issues.

• Veteran Potable Water Superintendent Sees Benefits Of Secondary Containment Equipment To Help Enable Use Of Chlorine Gas For Chlorination

  A veteran potable water production and treatment superintendent, currently overseeing potable water needs for a federal reservation, reports significant benefit from the availability of secondary containment equipment for chlorine gas storage, as part of a management strategy to help enable the use of that chlorination method. 

• The Reality Of Leaks: Cost-Effective Strategies For Real Water Loss Recovery

  Reducing water loss starts with proper perspective. In distribution systems that do not yet have permanent infrastructure monitoring for active leaks, even the approach to evaluating such infrastructure requires a new perspective. Here is how different technical approaches can make a difference, regardless of the age of the system or the pipe materials it uses.
